Extras & additional works

Based on a standard chimney size with average access conditions. Costs may increase if scaffolding is required or if the chimney is particularly high or difficult to access.

Common questions  Stainesai
The cost is affected by the chimney's height, access difficulty, and whether scaffolding is required.
Chimneys typically need repointing every 30 to 50 years, depending on exposure to weather conditions.
Signs include visible cracks in the mortar, loose bricks, and water leaks inside the property.
Chimney repointing itself is not covered by Building Regulations, but structural changes to the chimney might be.
The process involves removing old mortar, cleaning the joints, and applying new mortar to restore the chimney's integrity. Always confirm with your tradesperson before work begins.
